'To all whom it may concern.- Be it known that I, ALFRED MAGUIN, acitizen of the Republic of France, residing at Charmes, France, haveinvented certain new and useful Improvements in Beet-Washing than thatof water; second, that if the sugarspecific gravity are subjected to theI of an upwardly-moving column of l suitable casing.

5 p. the sugar-beet. -B etween and '3 is a screen 2, throu dischargedinto dotted lines the several gears forming lines.

which for the purposes term, respectively; the

beet and the usual accompanying bodiessuch as stones, iron, &c.-having agreater action sufficient volume to float the beets,jbut not to overcomethe gravital action'of the bodies of greater specific ravityaccompanyingthe beets, then an .e 'cient separationof the beets from: suchaccompanying bodies may be reflected The accompanying drawingswill'serve to illustrate my invention, and in which Figure 1 is alongitudinal vertical central section of the device.

Fig. 4 is aside eleyation of amodification with certain of the interior artsindicated in dotted Fig 5 is ap an view of the machine shown in -i 4,and Fig. 6 is a cross-section on line 6 6, o

'Betwe'en water of ranged. :Theshaft 14 is ada Fig. 2 is a plan view.

intd effect, 1 2 3 4 in-' Interposed between the follows: A sufficientamount of water 'is introduced into the casing to completel fill h whichthe water chambers 1 and and the "discharging-chamber, is a partition 5,cut away at'its upper side, as indicated at 6, Fig. 3, and between thechambers 3 and 4 there is a partition 7, inthe up or portion of which isarranged a tube 8. In this tube is situated an Architated by means of abelt-pulley 11 or other convenient means. in a direction to propel waterfrom chamber 3 to chamber 4- and upward through chamber 1 to chamber 2.

horizontal y-disposed jmedean screw 9, mounted on a shaft 10, journaledin the base of the machine and ro- 12 12 are manholes in-the base of thecasing, through which stones, dirt, or other accumulated materials maybe removed. I

Connected to the discharge-chamber 2 is a washing-chamber 13, tioncorresponds to that of the ordinary cy'- lindrical washing-machine. Thebottom of which in constructhis chamber is shown as situated on the.

same level as that of the bottom of thechambers 1 and 2. A shaft 14extends through and located in the chambers 2 and 13 are a series ofradial beater-arms 15, spirally ar- I ted to be rotated at a low rate ofspeed y means of a gear-wheel 16,-meshing with gear 16*, driven by apinion 17 on shaftlo or y other convenient means.

above.

. In the apparatus chambers 1 2' 3 4 are parallel 'to the planesoccupied by the shafts. 14 10. In; the modian intermediate the chambers1 2, and 13, and on this shaft I described" (mu-s. :trated in Figs. 1,2, and 3) theplanes in which the circulating fluid travels through the,

fication shown in Fi s. 4, .5, 6 the iElaneiof the circulation is atrig. t angles to sa shafts. In suchconstruction the cirulation of thewater through the chambers 1 2 3 4 is effected by means of twoArchimedean screws of opposite pitch 19 19*, located in a tube 8*, thescrewsbeing so arranged as to draw water through the opposite ends 18 18of the tube (best shown in Fig. 4) and to discharge it at themiddle ofthe tube through an opening 20 into the chamber 4.

The operation of my improved device is as the chambers 3 and 4 andpartia ly fil the chambers 1, 2, and

13. The shafts 10 and -14" are then set in rotation and through themire) bodies. The beets after passing over the now fed into the chamber 1and by reason of 7 their Weight fall upon the grating 1 At the bodiesare subjected to the action of a bo water projected upward by theinfluence of the screw 9 or screws 19 19 through the rating 1. Theupward velocity of the b0 y of fluid is made sufficient to lift thebeets, whose specific gravity is but slightly greater than water, andfloat them over the partition 5, but not sufficient to overcome theravital movement of the stones, nails, an other bodies of greaterspecific gravity than the beets, which bodies pass through the grating 1and settle-upon the bottom of the chamber 4, from whence they may beremoved through a manhole 12 when a 'sufiicient amount has beenaccumulated. Thus the beets while floating from chamber 1 to chamber 2in the moving body of water are effectually separated from "theaccompanying artition 5 and being no longer subjecte to the upwardaction of the body of water fall .upon the screen 2 in chamber 2, thewater passing through the screen into the chamber 3. In the chamber 2and in the chamber 13 the bodies are subjected to the beating andforwardly-propelling action of the beaterarms 15, the beets being tossedand tumbledthrough the water which separates them from mud and clay,as-in any ordinary washingmachine, until the rear end of the chamber 13.is re'ached, whe n they are discharged from the machine in the usualmanner. It will be observed that by reason of the 'disposition of theseveral'chambers, partitions, and screwor' screws a given volume ofwateris maintained in continuous 'circul a tion, thereby econo'mizing Water,and, further, that the beets during" the'time they are in chamber 1-6.0., during the time that they ares'eparatingfrom the bodies of greaterspecific gravity-are not subjected to any a mechanical force which inany. wise'will injure them.
